Arista Networks Platform and Cisco Nexus compete in the networking solutions category. Arista appears to have the upper hand due to its unified operating system, cohesive management features, and direct technical support, whereas Cisco Nexus offers flexibility and a range of features that could suit varied architectural needs.
Features: Arista Networks Platform provides a unified operating system that simplifies deployment without compatibility concerns. It also features stability and automation aspects, offering extensive network visibility and direct management through its CloudVision platform. Cisco Nexus is popular for its virtualization capabilities such as VDC and VPC, which allow high performance and flexibility in configurations. It is reliable and offers strong modularity for complex setups.
Room for Improvement: Arista Networks Platform could improve its documentation and expand feature integrations with security and cloud solutions. There's also room for better cost management and simpler integration with other systems. Cisco Nexus needs enhancements in documentation and software update support. While it offers advanced features, its pricing may limit wider adoption.
Ease of Deployment and Customer Service: Arista Networks Platform stands out for its seamless deployment and prompt, efficient technical support, typically involving direct interaction with engineers. This results in quicker problem resolution. Cisco Nexus offers competent support but doesn't match Arista's streamlined experience. Both technologies deploy effectively in on-premises and cloud environments.
Pricing and ROI: Arista Networks Platform is considered a premium product with high ROI potential, justified by operational efficiency and reduced deployment times, albeit with high initial costs. Cisco Nexus is slightly more affordable yet still costly but provides reliable value and a comprehensive feature set that offers solid ROI. Arista's higher costs may be a barrier for some, despite its technical benefits.
I saved between five to six hours using Arista Networks Platform, as it takes less time to actually add your APs to the dashboard and deployment is quite fast and easy.
I have seen a return on investment from using Arista Networks Platform in terms of fewer employees needed during installation and deployment.
In the data center, there is no comparison in terms of technicality or return of investment.
Speeding up our response times and reducing errors and incidents with automation and available APIs.
They provide instant support and maintain commitments regarding replacement products.
We would rate the customer support as a nine to 9.5 out of ten.
All network engineers from the organization were present in the program, and the Arista engineer provided a solution in less than five minutes.
For us, we have a time advantage because we know the solution, and the technological refresh is easier.
I would rate the support of Cisco an eight out of ten.
Arista Networks Platform's focus on GPU-based and high-speed switches is a smart move for next-generation AI-based data center solutions.
Scalability is a key feature of Arista, owing to the possibilities to manage the entire data center network from a single console.
We can easily scale up with Arista Networks Platform, as it is not difficult, and they have a platform that encourages scalability.
Arista is the only IT product that has the minimum vulnerabilities, so it is a very stable product.
I have not had any downtime using Arista Networks Platform.
We have been working with Arista Networks Platform for the past five years, and we can say it is stable.
Initially, the stability of Cisco Nexus, particularly with the ACI, was problematic due to unstable codes, requiring replacements.
Using AI, I can understand how my entire organization operates and what kind of applications are being used, what the peak times are, where there is a bottleneck if any exists.
Feature-wise, it addresses most customer requirements.
Arista Networks is currently less popular as they were initially more focused on data centers than campus networks.
When I talk about data centers, which are critical infrastructure and centralized application hubs, the Nexus platforms should be highly stable.
The solution is on-premises and stable.
It might be pretty expensive for other companies.
Compared to Cisco, Arista routers are significantly cheaper.
Arista products are perceived as costly, especially compared to competitors like Cisco.
As for the licensing model of Arista Networks Platform, I would describe it as moderate—neither too expensive nor too cheap compared to Cisco.
The price of Cisco Nexus is on the higher side due to the premium services Cisco offers.
All solutions are very expensive and not an economy solution.
Features include plug-and-play auto-discovery, allowing centralized configuration and management.
The best features Arista Networks Platform offers are the dashboards where you can see all your APs that have been deployed and installed across all locations, making it quite unique to access, manage, and monitor performance from that dashboard.
The most valuable features of Arista include low latency, scalability, and sustainability of the products.
The VPC feature of Cisco Nexus is great because it provides an active-active way of forwarding the traffic and avoids blocking any of the links.
For us, we have a time advantage because we know the solution, and the technological refresh is easier.
I encountered an issue where different models within the same series, the 95308 DC, do not support VPC between the EX series and FX3 series.
